So far all I've done is fly around a bit and after getting my controls configured this is really fun to fly around in! I love the VTOL VR simplified cockpit systems and startup, and the physics feel like a fantastic "just realistic enough to be interesting and require skill, but not so realistic that it's unflyable without a ton of practice."
It took me a couple flights to realize how easy it is to overload the helicopter. Flying with much less than full fuel made a huge difference. Maybe the default fuel could be lower, or maybe a warning to let players using the "default" flight model know they're going to have a hard time could be nice.
I haven't done any combat, just flown around a bit, but the only thing I think it needs with regards to the flight model is more trim options. Some way to apply rudder trim, since I don't have pedals, would be fantastic. I think my ideal trim setup mirrors DCS' with the push button force trim (that also applies to pedals) and then a return to center before you get authority again.
The foundation here for the flight model is rock solid though, and just throwing the little helicopter around is a blast.
